The Schedulev referred to in To all whom it 'may concern.- Be it knownthat I, WILLIAM `Knnnimif, otBelleville, in the county ot Essex andState of New Jersey, have invented a new and useful Improvement inGrates forFin-naces; and I do hereby declare that the following is afull, clear, and exact description thereof', which will enable othersskilled in the art .to reference being had to the accompanying drawingforming partof this specification.

Figure l reprvsents a vertical my improved grate.

Figure 2 is a vertical longitudinal section of the same; l

Similar let-ters of reference indicate.corresponding parts.'-

My'invention relates'to improvements in that class of grate-bars forfurnaces `which is provided with longitudinal, transversely-slottedbruce-bars. Hitberto these brace-bars have been so constructed as towarp or bend laterally, thus failing to perform their intended oihrce.

lt is the object oi' .my invention to obriate this difiiculty, and i Itconsists in applying a transverse bridge or support between the braceand Agrate-bars, as herein hown and described.

these VLettera Iigtent and making par( of the same A in the'drawingrepresents a grate, composed of a suitable number ot' grate-bars, n,which are held the proper distance apart by blocks b, er otherwise.

B is the brace. `The same has both ends bifurceted andseeured to themiddle grate-bars near to the ends 0f the same, thereby binding thegrate lengthwise, and causing it to retain its shape. v Y

'lo the middle of'the brace B is secured a tmnsverse bridge, C, whichhas upward projecting arms, c c, that reach to the several grate-bars,as shown in fio' 1.

These arms being secured tothe them the requisite distance apart.v

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The transversebridge C, secured to and combined with the brace'B, and providedwvithin'gers c, substantially as and for ,the purposes hereinV shown anddescribed.
